 spray;- applied by ground equipment for control of the boll weevil. J. 

 E' on. Entomol. 59: 114-116. 



During 196^ low-volume concentrate spray was evaluated for control of the boll 

 weevil, Anthonomus grandis Boheman. Technical nalathion applied with ground 

 equipment pave excellent weevil control. Commercially available nozzles 

 (Spraying .-/stems 730023 or equivalent) were fitted to a high-clearance sprayer. 

 With this rvstem it was possible to apply 25 ounces of technical nialathion (2 

 pounds) per acre. To apply smaller amounts of technical raalathion with these 

 nozzles, it was necessary to use water to make up the necessary volume. With 

 sufficient agitation water and technical malathion will stay in suspension. 

 When the water and malathion droplet strikes the cotton leaf the water eva- 

 porates leaving only the technical malathion. It is possible for this system 

 to be adapted to existing sprayers with very few modifications.

 Constituents of the boll weevil, Anthonomus grandis Boheman: III. Lipids 

 and fatty acids of subcellular particles of pupae. Comp. Biochem. Physiol. 

 43B:883-890. 



Phospholipids were the principal lipids in the microsomes, nuclei and mito- 

 chondria cf the boll weevil, Anthonomus grandis Boheman. The major fatty acid 

 in the phospholipids of the boll weevil was octadecadienoic acid (18:2) followed 

 by octadecenoic acid (18:1) and hexadescanoic acid (16:0). The weight of neutral 

 lipid varied in the subcellular particles, but the ratios of fatty acids remained 

 the ^ame. Phosphatidlyl choline predominated in the other subcellular particles 

 of the boll weevil. Triglycerides made up about 50 percent of the neutral lipids 

 of the nuclei, microsomes and cytoplasm. The principal neutral lipids of the 

 cell mitochondria were diglyceridas and raonoglycerides.
